Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 56 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.00716 |
| Opus 5 | $0.00020 | $0.00358 |
| Sonnet 5 | $0.00008 | $0.00143 |
| Haiku 4.5 | $0.00004 | $0.00072 |
Grade A, and why
tuist-generation-doctor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tuist Generation Doctor
Before invoking Apple-only binaries, confirm the execution context is macOS. From Windows or Linux, run those steps in a Mac SSH project or through an already configured remote transport; do not retry missing Apple binaries locally.
Use this skill to determine whether a Tuist-generated workspace problem is a project configuration issue, a dependency wiring issue, or a Tuist bug.
Triage Route
- Classify the failure stage:
- generation:
tuist generateortuist install - build: generated
.xcworkspaceexists butxcodebuildfails - runtime: app builds but crashes or behaves incorrectly
- generation:
- Capture the exact command, Tuist version, Xcode version, platform, scheme, and relevant manifest snippets.
- Reproduce on the local project first. If the issue is broad or suspicious,
retry with the latest Tuist release through
mise. - Reduce to a minimal reproduction before filing or fixing a Tuist-level bug.
Commands
tuist version
mise exec tuist@latest -- tuist install --path "$PROJECT_DIR"
mise exec tuist@latest -- tuist generate --no-open --path "$PROJECT_DIR"
For build-stage failures:
xcodebuild build \
-workspace "$PROJECT_DIR"/*.xcworkspace \
-scheme "$SCHEME" \
-destination "platform=iOS Simulator,name=<available iPhone simulator>,OS=latest" \
-derivedDataPath "$PROJECT_DIR/DerivedData"
For runtime-stage failures, launch the generated app:
xcrun simctl boot "<available simulator name or UDID>" 2>/dev/null || true
xcrun simctl install booted "$APP_PATH"
xcrun simctl launch --console-pty booted "$BUNDLE_ID"
Common Causes
- Missing
tuist installbefore generation. - Source/resource globs that omit files or include Swift files as resources.
- Package product type mismatches: static vs dynamic frameworks/libraries.
- Missing SDK dependencies, entitlements, Info.plist values, or resource bundles.
- Objective-C categories stripped from static dependencies; verify
-ObjCor targeted-force_load. - Generated workspace drift after manifest edits; regenerate before judging.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tuist-generation-doctor is a skill published in the GitHub repository Xopoko/build-swift-apps (45 stars, last pushed 15d ago), licensed MIT. It adds 40 tokens to every session and 716 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
